| Header: | Quickdraw.h | Carbon status: | Supported | |
Obtains a QDProcs structure with fields that point to basic QuickDraw’s standard low-level functions, which you can modify to point to your own functions.
void SetStdProcs (
QDProcs *procs
);
On return, a pointer to a QDProcs structure with fields that point to basic QuickDraw’s standard low-level functions. You can change one or more fields of this structure to point to your own functions and then set the basic graphics port to use this modified QDProcs structure. By changing these pointers, you can install your own functions, and either completely override the standard ones or call them after your functions have modified their parameters as necessary.
The functions you install in this QDProcs structure must have the same calling sequences as the standard functions.
The Color QuickDraw function SetStdCProcs is analogous to the SetStdProcs function, which you should use with computers that support only basic QuickDraw. When drawing in a color graphics port, your application must always use SetStdCProcs instead of SetStdProcs.
Supported in Carbon. Available in Carbon 1.0.2 and later when running Mac OS 8.1 or later.
